Satellite mobile communication terminal user identification and authentication method

Abstract

The invention discloses a satellite mobile communication terminal user identification and authentication method. The mobile communication terminal is based on a Beidou satellite system. The test method comprises the authentication mechanism and the encryption mechanism, wherein the authentication mechanism comprises the following steps: a public key is sent by a sender to a receiver, and a private key is saved by the sender; encryption is performed on data by the sender with the private key, and signed data is added; and verification and authentication are performed on the data by the receiver with the public key of the sender, and decryption is performed after the authentication is successful to obtain the data; and the encryption mechanism comprises the following steps: the public key is sent by the sender to the receiver, and the private key is saved by the sender; encryption is performed on data by the sender with the private key, and complete content is added; and decryption is performed on the data by the receiver with the public key, and after the authentication is successful, the data integrity is verified. The method of the invention can be used to effectively prevent various phenomenons, such as stealing calling, embezzlement, secret divulging, etc., in which mobile communication resources and services are used illegally in satellite mobile communication, and ensure satellite mobile communication network safety and ensure the legitimate rights and interests of satellite mobile communication operators and users.

Description

technical field [0001] The invention relates to a satellite communication leader, in particular to a method for user identification and authentication of a satellite mobile communication terminal. Background technique [0002] At present, satellite modulators are bound by hardware conditions and fixed configuration software. The encoding method, specification, and modulation method are fixed after delivery to users. In the future, a new encoding method, specification, and modulation method will need to be redeveloped. , the production cycle is relatively long, the versatility and portability are poor, the software cannot be upgraded online, and the future needs of users cannot be met. Therefore, it is necessary to design a general-purpose hardware platform first, and then realize arbitrary variable modulators such as coding methods, specifications, and modulation methods under the premise of the same hardware platform, so as to break through the bottleneck of hardware and fi...
